·         Identify the phases of the systems development life cycle (SDLC). Who participates   in SDLC? As a manager, how would you deal with potential problems when using this methodology?

 

Response:

 

The phases of the SDLC are as follows:

Initiation/Planning

During the Systems Initiation Phase, the scope, goals, schedule, and budget for the project should be determined. The scope and goals will have the largest impact on schedule and budget so these should be addressed accordingly. When established from scope and goals, the schedule and budget will create a baseline to base the project on. This will allow the people involved to know that from this point, any deviation in scope or goals will directly impact these two items.

Analysis

During the systems analysis phase the project team can evaluate more thoroughly the needs and problems that the project will be expected to solve. They can then determine what will work and what won't. This is a time to consult with system users to help understand what will be expected and what is needed in the project. This phase is where the feasibility of the project is determined, and can have a direct effect on the initial project scope or goals, which in turn could change budget or schedule and possibly even cause the project to be postponed or canceled.

Design

During the design phase, multiple solutions to the problems and needs from the analysis phase will be determined. This solution can be purchased or built by the company. Next the technical specifications and blueprints necessary for project completion will be determined. These blueprints will determine how the project is implemented in the business. Implementation - This is the phase where the project will be constructed and put into operation. As individual components of the project are put together, they must be tested. Finally the completed project must be tested for user expectations and functionality.

Maintenance

This phase is designed to keep the finished project running. There are often errors that make it through undetected, and these errors must be repaired, or the system improved, to continue functionality. It is possible also that the initial requirements have changed since the starting point, and these issues must be addressed as well. Essentially this can start a whole new “mini-project” in order to repair, or upgrade the project. All employees should participate in the life cycle at different points. Most potential problems are dealt with in the analysis and design phase. Other problems that occur during the cycle itself will have to be addressed accordingly using a preset change control procedure.

 As a manager I will make sure we as a team have laid a plan taking in account all unexpected and potential problems and design a system based on our best knowledge. When problems do arise, we will redesign the system for the best fit of our developmental project. Other problems occur when organization implement a software with no SDLC model. Development and troubleshooting are parts of proper documentation which is outlined in SDLC, therefore, with no SDLC, there are no documentations to support the development of the program.
